and to their agriculturally useful salts.

The invention furthermore relates to processes for the preparation of compounds of the formula I, to compositions comprising them, and to the use of these derivatives or compositions comprising them for controlling harmful plants.

Benzoylcyclohexenones are disclosed in the literature, for example in WO 96/26200.

However, the herbicidal properties of the prior-art compounds and their tolerance by crop plants are only moderately satisfactory.

It is an object of the present invention to find novel, in particular herbicidally active, compounds with improved properties.

We have found that this object is achieved by the 3-(4,5-dihydroisoxazol-5-yl)benzoylcyclohexenones of the formula I and their herbicidal action.

Furthermore, there have been found herbicidal compositions which comprise the compounds I and which have very good herbicidal action. Moreover, there have been found processes for the preparation of these compositions and methods of controlling undesired vegetation using the compounds I.

Depending on the substitution pattern, the compounds of the formula I may contain one or more chiral centers, in which case they are present as enantiomer or diastereomer mixtures. The invention relates both to the pure enantiomers or diastereomers and to their mixtures.

The compounds of the formula I can also be present in the form of their agriculturally useful salts, the type of the salt generally being of no importance. Suitable are in general the salts of those cations, or the acid addition salts of those acids, whose cations, or anions, respectively, do not adversely affect the herbicidal action of the compounds I.

Suitable cations are, in particular, ions of the alkali metals, preferably lithium, sodium and potassium, of the alkaline earth metals, preferably calcium and magnesium, and of the transition metals, preferably manganese, copper, zinc and iron, and also ammonium, it being possible here, if desired, for one to four hydrogen atoms to be replaced by C₁-C₄-alkyl or hydroxy-C₁-C₄-alkyl and/or a phenyl or benzyl, preferably ammonium, diisopropylammonium, tetramethylammonium, tetrabutylammonium, trimethylbenzylammonium, and furthermore phosphonium ions, sulfonium ions, preferably tri(C₁-C₄-alkyl)sulfonium and sulfoxonium ions, preferably tri(C₁-C₄-alkyl) sulfoxonium.

Anions of useful acid addition salts are mainly chloride, bromide, fluoride, hydrogensulfate, sulfate, dihydrogenphosphate, hydrogenphosphate, nitrate, hydrogencarbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate, and the anions of C₁-C₄-alkanoic acids, preferably formate, acetate, propionate and butyrate.

The 3-(4,5-dihydroisoxazol-5-yl)benzoylcyclohexenones of the formula I can be obtained by various routes, for example by the following process:

Process A:

Reaction of cyclohexenones of the formula II (where R¹²=OH) with an activated carboxylic acid IIIα or a carboxylic acid IIIβ which is preferably activated in situ, to give the acylation product which is subsequently subjected to a rearrangement reaction.

L¹ is a nucleophilically displaceable leaving group such as halogen, e.g. bromine or chlorine, hetaryl, e.g. imidazolyl or pyridyl, carboxylate, e.g. acetate, trifluoroacetate and the like.

The activated carboxylic acid can be employed directly, such as in the case of the carbonyl halides, or generated in situ, for example with dicyclohexylcarbodiimide, triphenylphosphane/azodicarboxylic ester, 2-pyridine disulfide/triphenylphosphane, carbonyldiimidazole and the like.

If appropriate, it may be advantageous to carry out the acylation reaction in the presence of a base. The reactants and the auxiliary base are expediently employed in equimolar amounts. An excess of the auxiliary base, for example 1.2 to 2.5 mol equivalents, especially 1.2 to 1.5 mol equivalents, based on II, may be advantageous under certain circumstances.

Auxiliary bases which are suitable are tertiary alkylamines, pyridine or alkali metal carbonates. Solvents which can be employed are, for example, chlorinated hydrocarbons such as methylene chloride, 1,2-dichloroethane, aromatic hydrocarbons such as toluene, xylene, chlorobenzene, ethers such as diethyl ether, methyl tert-butyl ether, tetrahydrofuran, dioxane, polar aprotic solvents such as acetonitrile, dimethylformamide, dimethyl sulfoxide, or esters such as ethyl acetate, or mixtures of these.

If carbonyl halides are employed as activated carboxylic acid component, it may be advantageous to cool the reaction mixture to 0-10° C. when adding this reactant. The mixture is subsequently stirred at 20-100° C., preferably at 25-50° C., until the reaction is complete. Work-up is carried out in the customary fashion, for example the reaction mixture is poured into water and the product of interest is extracted. Solvents which are suitable for this purpose are in particular methylene chloride, diethyl ether and ethyl acetate. After the organic phase has been dried and the solvent has been removed, the crude ester can be employed without further purification in the rearrangement reaction.

Rearrangement of the esters to give the compounds of the formula I is expediently carried out at temperatures of from 20 to 40° C. in a solvent and in the presence of a base and, if appropriate, with the aid of a cyano compound as catalyst.

Solvents which can be used are, for example, acetonitrile, methylene chloride, 1,2-dichloroethane, dioxane, ethyl acetate, toluene or mixtures of these. Preferred solvents are acetonitrile and dioxane.

Suitable bases are tertiary amines such as triethylamine, pyridine or alkali metal carbonates such as sodium carbonate or potassium carbonate, which are preferably employed in equimolar amounts or up to a four-fold excess based on the ester. By preference, triethylamine or alkali metal carbonates are employed, preferably in twice the equimolar ratio based on the ester.

Suitable cyano compounds are inorganic cyanides, such as sodium cyanide, potassium cyanide and organic cyano compounds such as acetone cyanohydrin or trimethylsilyl cyanide. They are employed in an amount of 1 to 50 mol percent based on the ester. Preferably, acetone cyanohydrin or trimethylsilyl cyanide are employed, for example in an amount of 5 to 25, preferably 5 to 15, in particular 10, mol percent based on the ester.

Work-up can be carried out in a conventional manner. For example, the reaction mixture is acidified with dilute mineral acid, such as 5% strength hydrochloric acid or sulfuric acid, and extracted with an organic solvent, for example methylene chloride or ethyl acetate. The organic extract can be extracted with 5-10% strength alkali metal carbonate solution, for example sodium carbonate or potassium carbonate solution. The aqueous phase is acidified, and the precipitate which forms is filtered off with suction and/or extracted with methylene chloride or ethyl acetate, dried and concentrated.

(Examples of the synthesis of hydroxypyrazole esters and of the rearrangement of the esters are given for example in EP-A 282 944 and U.S. Pat. No. 4,643,757).

As a rule, the starting compounds are employed in an equimolar ratio. However, it may also be advantageous to employ one or the other component in excess.

If appropriate, it may be advantageous to carry out the reaction in the presence of a base. The reactants and the auxiliary base are expediently employed in equimolar amounts. Under certain circumstances, an excess of the auxiliary base, for example 1.5 to 3 mol equivalents based on II, may be advantageous.

Suitable auxiliary bases are tertiary alkylamines such as triethylamine or pyridine, alkali metal carbonates, e.g. sodium carbonate or potassium carbonate, and alkali metal hydrides, e.g. sodium hydride. Triethylamine and pyridine are preferably used.

As a rule, the starting compounds are employed in an equimolar ratio. However, it may also be advantageous to employ one or the other component in excess.

If appropriate, it may also be advantageous to carry out the reaction in the presence of a base. The reactants and the base are expediently employed in equimolar quantities. An excess of base, for example 1.5 to 3 mol equivalents based on I where R⁸=Hal, may be advantageous under certain circumstances.

The esters of the formula IIIγ or the halogen compounds of the formula VI can be synthesized by subjecting nitrile oxides and corresponding alkenes of the formula VIII or IX to a 1,3-dipolar cycloaddition reaction.

The nitrile oxides are generated in situ in a conventional manner.

A solution of 2.3 g (7.7 mmol) of 2-methyl-3-(3-methyl-4,5-dihydroisoxazol-5-yl)-4-methylsulfonylbenzoyl chloride in 50 ml of acetonitrile was added dropwise at 0-5° C. to a solution of 0.86 g (7.7 mmol) of 1-hydroxycyclohex-1-en-3-one and 2.13 ml (15.4 mmol) of triethylamine in 50 ml of acetonitrile. After the mixture had been stirred for three hours at room temperature, a further 0.64 ml (4.6 mmol) of triethylamine and 0.16 g (15 mmol) of trimethylsilyl cyanide were added and the mixture was stirred for twelve hours at room temperature. The reaction mixture was then stirred into 800 ml of water and washed with methylene chloride. The aqueous phase was then brought to pH 4 using 10% strength hydrochloric acid and extracted with methylene chloride. After the organic phase had been dried, the solvent was removed and the residue was taken up in diethyl ether and digested. The resulting residue was filtered off with suction. This gave 1.3 g (3.3 mmol; 43% of theory) of the title compounds.

The 3-(4,5-dihydroisoxazol-5-yl)benzoylcyclohexenones of the formula I and their agriculturally useful salts, both in the form of the isomer mixtures and in the form of the pure isomers, are suitable as herbicides. The herbicidal compositions comprising compounds of the formula I effect very good control of vegetation on non-crop areas, especially at high rates of application. In crops such as wheat, rice, maize, soya and cotton, they act against broad-leaved weeds and grass weeds without damaging the crop plants significantly. This effect is observed especially at low application rates.

Depending on the application method in question, the compounds of the formula I or herbicidal compositions comprising them can additionally be employed in a further number of crop plants for eliminating undesired plants. Examples of suitable crop plants are:

Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Beta vulgaris spec. altissima, Beta vulgaris spec. rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Camellia sinensis, Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arboreum, Gossypium herbaceum, Gossypium vitifolium), Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usitatissimum, Lycopersicon lycopersicum, Malus spec., Manihot esculenta, Medicago sativa, Musa spec., Nicotiana tabacum (N.rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spec., Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Ribes sylvestre, Ricinus communis, Saccharum officinarum, Secale cereale, Solanum tuberosum, Sorghum bicolor (s. vulgare), Theobroma cacao, Trifolium pratense, Triticum aestivum, Triticum durum, Vicia faba, Vitis vinifera and Zea mays.

Moreover, the compunds of the formula I can also be used in crops which tolerate the action of herbicides due to breeding, including recombinant methods.

The compounds of the formula I, or the herbicidal compositions comprising them, can be employed, for example, in the form of directly sprayable aqueous solutions, powders, suspensions, also highly-concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading or granules, by means of spraying, atomizing, dusting, spreading or pouring, or as a seed treatment or by mixing with the seed. The use forms depend on the intended purposes; in any case, they should guarantee the finest possible distribution of the active ingredients according to the invention.

The herbicidal compositions comprise a herbicidally active amount of at least one compound of the formula I or of an agriculturally useful salt of I and adjuvants conventionally used for the formulation of crop protection products.

Suitable inert auxiliaries are essentially: mineral oil fractions of medium to high boiling point such as kerosene and diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, e.g. paraffins, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, alkylated benzenes and their derivatives, alcohols such as methanol, ethanol, propanol, butanol and cyclohexanol, ketones such as cyclohexanone, strongly polar solvents, e.g. amines such as N-methylpyrrolidone, and water.

Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersable granules by adding water. To prepare emulsions, pastes or oil dispersions, the 3-(4,5-dihydroisoxazol-5-yl)benzoylcyclohexenones, as such or dissolved in an oil or solvent, can be homogenized in water by means of wetters, tackifiers, dispersants or emulsifiers. However, it is also possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil which are suitable for dilution with water.

Suitable surfactants (adjuvants) are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, e.g. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, of alkyl- and alkylarylsulfonates, of alkyl sulfates, lauryl ether sulfates and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols, and of fatty alcohol glycol ether, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene, or of the naphthalenesulfonic acids, with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenyl and tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene alkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignin-sulfite waste liquors or methylcellulose.

Powders, materials for spreading and dusts can be prepared by mixing or concomitantly grinding the active substances with a solid carrier.

Granules, for example coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers. Solid carriers are mineral earths such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas and products of vegetable origin such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders or other solid carriers.

The concentrations of the compounds of the formula I in the ready-to-use products can be varied within wide ranges. In general, the formulations comprise approximately from 0.001 to 98% by weight, preferably 0.01 to 95% by weight, of at least one active ingredient. The active ingredients are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).

The formulation examples below illustrate the preparation of such products:

Finely distributing the mixture in 20000 parts by weight of water gives a spray mixture which comprises 0.1% by weight of the active ingredient.

V. 3 parts by weight of the active ingredient No. 2.5 are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 3% by weight of the active ingredient.

VI. 20 parts by weight of the active ingredient No. 2.9 are mixed intimately with 2 parts by weight of calcium dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol/urea/formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.

VII. 1 part by weight of the active ingredient No. 2.5 is dissolved in a mixture composed of 70 parts by weight of cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and 10 parts by weight of ethoxylated castor oil. This gives a stable emulsion concentrate.

The compounds of the formula I or the herbicidal compositions can be applied pre-emergence, post-emergence or together with the seed of a crop plant. It is also possible to apply the compounds of the formula I or the herbicidal compositions by sowing the seed, of a crop plant, which has been pretreated with the herbicidal compositions or active ingredients. If the active ingredients are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed with the aid of the spraying equipment in such a way that they come into very little contact, if any, with the leaves of the sensitive crop plants, while the active ingredients reach the leaves of undesired plants growing underneath, or the naked soil surface (post-directed, lay-by).

Depending on the intended aim of the control measures, the season, the target plants and the growth stage, the application rates of compound of the formula I are from 0.001 to 3.0, preferably from 0.01 to 1.0, kg of active substance (a.s.) per ha.

To widen the spectrum of action and to achieve synergistic effects, the 3-(4,5-dihydroisoxazol-5-yl)benzoylcyclohexenones of the formula I can be mixed with a large number of representatives of other groups of active ingredients which act as herbicides or as growth regulators and applied together with these. Suitable components in mixtures are, for example, 1,2,4-thiadiazoles, 1,3,4-thiadiazoles, amides, aminophosphoric acid and its derivatives, aminotriazoles, anilides, aryloxy-/heteroaryloxyalkanoic acids and their derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-(hetaroyl/aroyl)-1,3-cyclohexanediones, heteroaryl aryl ketones, benzylisoxazolidinones, meta-CF₃-phenyl derivatives, carbamates, quinolinecarboxylic acid and its derivatives, chloroacetanilides, cyclohexenone oxime ether derivatives, diazines, dichloropropionic acid and its derivatives, dihydrobenzofurans, dihydrofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl ethers, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phenyl-3,4,5,6-tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- and heteroaryloxyphenoxypropionic esters, phenylacetic acid and its derivatives, phenylpropionic acid and its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers, sulfonamides, sulfonylureas, triazines, triazinones, triazolinones, triazolecarboxamides and uracils.

Moreover, it may be advantageous to apply the compounds of the formula I, alone or in combination with other herbicides, or in the form of a mixture with other crop protection agents, for example with agents for controlling pests or phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions, which are employed for treating nutritional and trace element deficiencies. Nonphytotoxic oils and oil concentrates can also be added.

USE EXAMPLES

The herbicidal action of the 3-(4,5-dihydroisoxazol-5-yl)benzoylcyclohexenones of the formula I was demonstrated by the following greenhouse experiments:

The culture containers used were plastic flower pots containing loamy sand with approximately 3.0% of humus as substrate. The seeds of the test plant were sown separately for each species.

For the pre-emergence treatment, the active ingredients, which were suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transparent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants unless this was adversely affected by the active ingredients.

For the post-emergence treatment, the test plants were first grown to a plant height of from 3 to 15 cm, depending on the plant habit, and only then treated with the active ingredients which had been suspended or emulsified in water. To this end, the test plants were either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to the treatment. The rate of application for the post-emergence the treatment was 125 or 62.5 g of a.s. (active substance) per ha.

Depending on the species, the plants were kept at temperatures of from 10 to 25° C. or from 20 to 35° C. The test period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

Evaluation was carried out using a scale of from 0 to 100. 100 means no emergence of the plants, or complete destruction of at least the aerial parts, and 0 means no damage or normal course of growth.

The plants used in the greenhouse experiments belonged to the following species:

Scientific name Common name Amaranthus retroflexus redroot pigweed Chenopodium album lambsquarters (goosefoot) Digitaria sanguinalis hairy fingergrass Panicum dichotomiflorum fall panicum Polygonum persicaria ladysthumb Solanum nigrum black nightshade Stellaria media common chickweed Matricaria false chamomile Brachiaria platyphylla broadleaf signal grass Lamium amplexicaule henbit

When rates of application of 125 or 62.5 g/ha a.s. were employed, the compound 2.4 was very effective against Brachiaria platyphylla, lambsquarters, Lamium amplexicaule, chamomile and common chickweed. Equally, the compound 2.9 controlled redroot pigweed, lambsquarters, hairy fingergrass, ladysthumb and fall panicum very efficiently under analogous conditions. Used pre-emergence at application rates of 125 or 62.5 g/ha, the compound 2.5 controls redroot pigweed, hairy fingergrass, lambsquarters and black nightshade highly efficiently.
